ereg_replace

[UKlee]

I have items being braught from my db which start with letter some times these are FLY and some times depending on the item FL how can I use ereg to replace both basically I wish to remove the letters from the begining but not the end of the output.

$bookno='FLY299A'; would like this to just show 299A

or sometimes it's like this 

$bookno='FL299A' looking to output 299A again




echo ereg_replace ("FLY", " ", $bookno);

the above would work for the first example but how do i get this to work for both items any help would be great .

thanks in advance

ereg_replace ('^(FLY|FL)', '', $bookno);

//or use str_replace()

$search_text = array('FLY', 'FL');

str_replace($search_text, '', $bookno);

Here are two seperate methods. You can have any alphabetical prefix (FLY, FL, DRY, etc.) and they'll keep on working.

$bookno = 'FL299A';
print strpbrk($bookno, '01234567789'); // strpbrk is only availabe in PHP5 i believe

preg_match('[\d\w+]', $bookno, $match);
print $match[0];

this worked superb and thank you very much esukf for looking and helping

however I was wondering if i could also replace the B or A for Bravo or Alpha based on the letter following the numbers is this possible.

they come from a table and would be like FLY229A or FLY299B or FL299A or B I can now remove the FL or FLY Part but was wondering if I can now change the A or B to ALPHA or Bravo accordingly.

kind regards

There are probably easier ways but this should work. I tried to keep this as readable as possible.

$bookno = 'FL299A';
$handle = array('A' => 'Alpha', 'B' => 'Bravo', 'C' => 'Charlie');  // handle array
preg_match('[\d\w+]', $bookno, $match);  // get string without prefix and assign to match
$tempbook = $match[0];
$pos = strlen($tempbook -1);  // get last character position
$char = $tempbook{$pos};  // get last character
$tempbook = substr($tempbook, 0, ($pos));  // strip ending
$newbookno = $tempbook . $handle[$char]; // add handle
print $newbookno;

Thank you both very very much both worked great to start your code samudasu is outstanding and does exactly what I needed it to do. I shall look at this and figure this all out and hope to adapt and use this for other items in the future once again thank you .

Kind regards

I don't think i would say it's outstanding but thanks anyways. Looking back on it, i noticed some thing that were unnecessary and might have been confusing so i took them out. Here is a revised version. Good luck with it.

$bookno = 'FL299A';
$handle = array('A' => 'Alpha', 'B' => 'Bravo', 'C' => 'Charlie');  // handle array
preg_match('[\d\w+]', $bookno, $match);  // get string without prefix and assign to match
$tempbook = $match[0];
$char = substr($tempbook, -1);  // get last character (A, B, C, etc.)
$tempbook = substr($tempbook, 0, -1);  // strip the last chacter
$newbookno = $tempbook . $handle[$char];  // add handle
print $newbookno;

EDIT: Yet another edit. Sorry but it keeps getting shorter.

$bookno = 'FL299B';
$handle = array('A' => 'Alpha', 'B' => 'Bravo', 'C' => 'Charlie');  // handle array
preg_match('[\d\w+]', $bookno, $match);  // get string without prefix and assign to match
$tempbook = $match[0];
list($tempbook, $char) = sscanf($tempbook, "%d %s"); // split numeric and alphabetical values, assign them into variables 
$newbookno = $tempbook . $handle[$char];  // add handle
print $newbookno;
